As to what lawyer decided to make a real life case out of this after watching the show too much, I'm not sure..
So you are cool with her being rejected for how she looks on the surface?
This is a false reduction of my argument into something that aligns it with racism/feminism etc, a very cheap example of "pulling the card;" but your argument is absurd.
"How she looks on the surface" does not mean her race, sexual orientation, gender or anything that is not her choosing. However, she chose to go into the bathroom, get out bleach, go and dye her hair pink. This is done as a statement, expressing her style; and is completely her choice. Would you hire someone who carved a swastika into their forehead or had a nice SS tattoo on their neck? Would that be rejecting them by how they look on the surface, or ist hat a choice they've made to send a bold statement with their appearance?
If not, then what's the difference between that and not hiring someone with pink hair because you think they are sending a statement that says "I'm independent/insubordinate and don't care what others think?"
Is that a good message to send to would-be developers/technologists? Dye your hair pink, go into interviews, watch as your shown the door for clearly caring more about being a hipster than having a good job.
Seriously, there are very few serious professional technologists who dye their hair flamboyant colors, regardless of gender.
The culture of Silicon Valley and California in general is to sound positive all the time and avoid the negative -- people would much rather say nothing or offer platitudes than say "no". This forms part of the problem leading to depression -- everyone is "fake" and say things for political reasons, constantly on social networking talking up their accomplishments and that of their company. Of course, most of it is smoke and mirrors. Also the tech scene can be very pretentious and it takes a lot to "keep up with the Joneses" and stay in the social circles they prize. It becomes too much for many and they become depressed and fade away, replaced at their companies by the VC board. And some willing 20-something then comes and tries to fill their shoes and the cycle repeats.
No one wants to hire a depressed person. No one wants to go on dates with a depressed person (well, at least not many people -- negative/depressed dating site profiles don't get many replies). So, they conceal it until they break with full knowledge that when they break, they'll simply be replaced or their company will simply fail.
